The one thing most people do when they go to work, wake up in the morning or head on to school do is check their emails. As a communication tool, it is one of the most efficient ones available today and we use them for almost every aspect of our lives. Our mail client is the vessel that carries all our communicae’ and while we would like it to be trouble free, this isn’t usually the case. Spam is a great problem nowadays and it pervades the entire world like some digital endemic we cannot escape from.

Coined as a derogatory term towards mass emailing and marketing, spam has now taken on new and more complex forms, with methods that boggle even some anti virus systems and find themselves in our inbox. What is a mild irritant at first can turn into something more dangerous if not treated early. This is especially so when you are in business and you need to get your emails in order. Nothing can slow your day, frustrate you, elevate your stress levels and put a clog in your business like spam. How does it get there in the first place? Well there are many ways that a spam network can get a hold of your email.

There are email sniffers out there who are dedicated worms, which track the digital network for any loose email addresses. The compile a list of literally millions of emails a day based on searches through forums, e-zines, websites, databases and collectives online. There are also worms which infect a single email address, steal the password and then retrieve their email list, which then each one gets infected, sending all the information back to a central server or a gate way in the internet where the hacker will store all his information. This is the deadly cycle of email stealing that goes on daily on the internet because spam networks will pay good money for a huge collection of emails.

These spam operators usually root themselves in countries where it is not recognised as illegal and operate from that jurisdiction, which explains why spamming is still a giant problem today. It is the sum total of the lowest common denominators of online marketing as is considered a despicable way to market goods. Most of the goods that come in spam usually are male organ enlargers or pornography, so based on the type of market that associated itself with this sort of marketing, you then know the debased level of digital existence that it belongs to. In any case, the only draw of this is the percentages.

With usually no more than a 0.1% hit rate with spam emailing, out of 20 million emails, that is still generated profit for the company. They have sophisticated technology behind them and a team of hackers, so the general advice is to get a good spam block system to get your emails in order and protect the integrity of your mail client.

Unsolicited junk e-mail or spam is an unfortunate reality that comes with the use of internet although web users are affected by it in different degrees. At times it becomes difficult for e-mail account holders to distinguish between genuine messages and spam and this makes it a constant bother to many individuals as well as business enterprises. There are several programs that have been created to block out spam from e-mail inboxes and among the main components to aid this process is what is known as a spam blocker or Exchange spam filter, which is installed within exchange servers. A spam filter for Exchange Server is capable of scanning messages that have spam keywords and spam headers. After the spam messages have been identified, the Exchange spam filter server will inform the user which mails have been treated as spam. This will significantly reduce the chances of attacks from viruses and malware.

There is an option of setting the server to block out blank senders; however this is not advised because some important documents such as read receipts do not have sender fields. The filtering process can be done without the sender knowing and this is advised because it can significantly reduce the server load. Most exchange servers have an inbuilt ORFilter or Open Relay Filter as well as a Realtime Blackhole List or RBL capability, which means that there will not be any need for any third party software for filtering spam.

The initial process is to go to the delivery settings for messages and clicking on ‘new’ so as to add another connection filter. From here, the preferred Realtime Blackhole selection will be chosen and the OK button clicked. There are some exceptions to these specifications that can be chosen by clicking on exceptions and filling in the desirable settings. There will be a warning pop out stating that a SMTP virtual server will need to be enabled for the process of filtering. One will have to go to SMTP virtual server properties and click on ‘edit’. The checkbox with ‘Apply Connection Filter’ should be checked. After clicking OK, exit completely.

There may be a need for third party spam filter software applications; however they are quite costly meaning that small enterprises and individuals will find it difficult to invest in it. In most cases though, the Exchange spam filter embedded within the exchange server is enough to block out most of the threats from spam. There is an option that can be used to store junk mail and its configuration may be done by defining a particular threshold that is based upon the SCL rating. By doing this, the system will be able to distinguish whether a message is to be put into the inbox or in a folder for junk e-mail.

The Exchange spam filter within the exchange server makes use of several combinations that are supposed to decipher the composition of messages and identify whether they are spam. It is for this reason that the configuration should be appropriately done to ensure that the spam filter within Exchange will be able to effectively carry out all the necessary procedures to keep out unsolicited e-mails. Users, who want to control or avoid spam mail, will have a better alternative by using the Exchange filter for spam emails.

Email marketing continues to grow as a great alternative for not only marketing advertisements and product offers to your customers, but also as way to continue a dialog with your customers that keeps them engaged and coming back to your websites. This combination of offers, ads, and newsletters begins to increase your monthly email volume. It is at this point that you begin to experience some of the challenges of sending bulk email out into the Internet, especially to email addresses that belong to the large ISPs like Yahoo, Hotmail and AOL. You begin to realize that the infrastructure you have in place may now be inadequate to handle the level of email you are sending. Your email is getting stuck in queues for hours, or some email stops getting delivered altogether to your Hotmail addresses. If this is happening, you may need to consider an upgrade to a new level of commercially available email software.

One of the main pieces of an email marketing system is the SMTP server. Why is this server so important? Your SMTP server or MTA (mail transfer agent) is the sending engine of your bulk email system. This server receives generated email from your email marketing application, determines what email domains to deliver it to, and provides the transport and delivery of those messages to the various email domains on your list. Without the SMTP server, your email doesn’t make it out of your site. Picture a pile of un-delivered envelopes that just sit on your desk because there is no post office to sort and delivery them to their destination. In the early days of email marketing when volumes were much lower, many people turned to either their internal email servers like Exchange, or they used freely available SMTP servers like Sendmail, Postfix, or Microsoft IIS SMTP server.

But as the use of email for marketing purposes went up and volumes increased, two things began to happen. One was that using in-house email systems built for personal email communications began to break down because they were not built to handle large volumes of bulk email. Second, was that freely available SMTP servers were not able to adequately address the delivery challenges of sending bulk email to the large consumer ISP domains. These challenges include processing email bounces, throttling email to specific domains and the support for email authentication standards like DomainKeys, DKIM, SenderID and SPF.

Here are some trouble signs for look for:

Long Delivery Times

One main reason you may be experiencing long delivery times for even several thousand email messages is that your SMTP server simply cannot keep up with the load of not only parsing your email messages, but also with all of the DNS lookups that need to take place during delivery. A second reason why you may be experiencing long delivery times is that the ISP you are delivering to is deferring your email. Email gets deferred for several reasons: 1) the combination of your To, From, and IP address are not familiar with the ISP so as an anti-spam technique they will temporarily defer receiving email from your IP address; and 2) your SMTP server is sending email at a rate that is beyond the threshold of the ISP so they may again temporarily defer the email coming from your IP address.

Mail to Specific Domains Is Not Delivered

If email to a specific domain like Yahoo.com or Hotmail.com is not delivered, it may mean that the ISP has put your IP address on a blacklist. This can happen for several reasons. One reason is that your email is generating too many user complaints; people reviewing your email are designating it as spam. Another reason could be that you continually send email at a rate above the thresholds of the ISP. An ISP may choose to put your IP on a blacklist and refuse email from that IP if it detects that you may be a spammer based on your sending patterns. A third reason could be that you are sending too many bad email addresses to the ISP. If your list contains invalid email addresses, and you continually send to those bad email addresses, an ISP may consider you a spammer and put your IP address on a blacklist.

Email Responses Remain Flat or Decrease While Volume Increases

The law of averages would assume that based on a certain percentage of responses per number of total messages, the number of responses would increase at that same percentage as email volume increases. If you are seeing a decrease or a flat percentage as your email volume increases, it may point to an overall deliverability problem that exists within your email system. This decrease in deliverability may be caused by some or all of the problems discussed above. Overall deliverability of your email can depend on many factors including the use of email authentication standards, your DNS configuration, your sending frequency, the quality of your lists, and the throttling of your email within the guidelines of your ISP.

You will experience these issues once your email approaches several hundred thousand to several million a month. Freely available and inexpensive SMTP servers were never architected to support high levels of email, or the deliverability issues surrounding delivery of email to the large ISPs. Consider looking at an enterprise level, commercially available SMTP Server or a Hosted SMTP Relay Service provider that were built for the demands of both high throughput and high deliverability to protect your email marketing investment.

Working with business Exchange email servers can be severely hampered without a quality Exchange spam filter. This component is used to filter out any unsolicited e-mails that are sent from various sources via the internet. Without any blocking device for spam emails, it is a cumbersome task for web users to sort out wanted or genuine mails from unsolicited mails. The exchange spam filter is strategically embedded between the PC and the server for mail. There is no web user who is completely protected from spam but depending on the measures that are put in such as using the spam filter for Exchange; the threats can be significantly minimized.

A spam filter within an Exchange server is basically software based program, which has the ability to spot, separate and erase any e-mails that have the characteristics of spam. The term spam filter and spam blocker is normally used interchangeably although there is a slight difference between these two tools. With filters, the mail that is directed to a web user’s inbox is divided into non spam and spam categories. The recipient of the mail will then be expected to either open or delete the mails one by one. With an Exchange spam filter the mails that fit the description of spam are instantly blocked and removed.

The key e-mail service providers such as Google G-mail and Yahoo mail use spam filters, which allow users to appropriately sort their e-mails. Many spammers have been able to fool this filtering mechanism, which means that there may be a greater chance that plenty of spam may not be categorized as junk mail. As a result of this, there may be a need to add additional anti spam devices. However, if an Exchange spam filter or blocker is configured correctly, it can be sufficiently effective for reducing the exposure to computer infections from viruses, malware, adware as well as other potentially harmful computer applications.

Apart from the harmful applications that spam predisposes users to, it also has the disadvantage of bulking inboxes with mostly unnecessary mail. It is only with an Exchange spam blocker that threats can be dealt with effectively unlike firewalls and anti-viruses that are not able to deal comprehensively with web threats. The choice of a spam blocker or filter for an exchange server should be done carefully and installed according to the appropriate demands and needs. For instance, an individual is not likely to have the same requirements as a large corporation. The type of anti spam application chosen should also depend on other additional factors including the filter compatibility, ease of use and ability to be customized or upgraded.

Any Exchange spam blocker or filter solution should have professional assistance when it comes to installation and maintenance. The spam filter for exchange will guarantee that the system runs optimally and does exactly what it is supposed to do. Reviews for software companies should be carried out before acquiring any anti spam exchange filter application. This will ensure that a company has the required credibility to offer the highest quality product.

Spam or unsolicited electronic mails are common features in our inboxes when we try to access or read our mail boxes online. The sources of these mails are usually product or service providers who want to advertise themselves through the website without your consent. They employ the service of softwares or robots to generate email address randomly and send these mails in bulk to all recipients.

Most robust web portals with mail servers such as Yahoo, Google mail, MSN have built in applications on their website whereby such mails are not received in the inbox but are diverted into a special box meant for unsolicited mails. This application is not entirely foolproof as some spam mails still manage to find their way into the inbox of the user. Spam mails are loathed by every web user because apart from the time that it causes to be wasted it could infect and damage your system with computer viruses not to talk less of infections that could breach your financial security.

Since eliminating spam mails can not be achieved out rightly reducing its menace is an alternative worth considering. One method being used to reduce spam mails is the challenge response system, this application also known generally as anti-spam software is designed to transfer the workload from the receiver of the mail to the originator of the mail. The trick behind this system is that the sender of those unsolicited mails would not have the time to start sending confirmation for million of mails he has sent out whereas a recognized sender could do so because he really needs to get across to you and could afford the time to reconfirm his intention.

One other strategy being adopted by some user to reduce the level of spam mails they receive in their inbox involves setting up a disposable email address which is normally used for registering on some web sites which are not really important so that mails come from them or their affiliates you can’t be bothered by them. In addition, to this tip it is also advisable not to leave your email address on a website or an online forum because information submitted here are not really kept in confidence but will either be given to affiliates, sold to spammers or web application devised for such will capture and send your mailing address into a database for use in spamming. Technically it is possible to encrypt your email address so that unauthorized users can not gain access to it but to tread on the safe path avoid publishing your mailing details on forums.

In the event whereby all efforts are sanitising your mail box from spam mails fails all you need to resort to is filtering your mail box. This system implies activating a set of rules normally integrated into the web design of most popular mail servers on the internet. On the other hand, you could purchase an online internet anti virus software which filters your mails before it gets to the mail server.

One thing that has plagued more or less all the Internet users is Spam. Thus, the biggest ask of todays Internet age is Anti Spam tools.

As the usage of internet is multiplying day after day, e-mail has become the most powerful and desirable means of communication. But some people are trying to annihilate its great reputation by introducing the spam into it. Spam is nothing but unsolicited, unwanted, irrelevant or inappropriate e-mail. They are also known as junk mails. Spam mails are basically aimed at wasting the time and as a result, money of the individuals who are at the receiving end. Many people get annoyed when they see their inboxes full of junk mails, which are hidden between the legitimate ones. This situation may lead to chaos as these people may inadvertently delete the legitimate e-mails while deleting the spam. Also, the spam mails can cause unnecessary burden over the servers by uploading lots of redundant data over them. Moreover, they may even contain viruses, spyware and trojans which can damage the whole system of the receiver.

Hence, people who are acquainted with these ill effects of the spam mails are on the constant look out for better and more advanced Anti Spam solutions to get rid of this menace. Therefore big software companies are continuously trying to develop Anti Spam solutions, spam blockers and e-mail spam filters. Anti Spam solutions are basically designed to check the sender’s name and address and filter the spam e-mails according to a black list of spammers they own. They may also check the recipients’ names and addresses and filter the spam mails according to certain parameters decided by them. Some Anti Spam solutions also use content filtering or Bayesian Logic. They can scan the e-mails and search for certain words or phrases which are common in most spam mails like ‘viagra’ or ‘click here’ and filter the spam e-mails accordingly.

However, these Anti Spam solutions are not infallible. If the software companies are trying to develop more and more advanced ways to block and filter spam, the spammers are also not sitting idle. They are also constantly inventing new ways to hoodwink these Anti Spam programs and cause havoc in the world of internet. Moreover, most of these Anti Spam solutions are not reliable as they may delete some very necessary e-mail taking them as spam. This might happen if a legitimate sender makes use of some of the terms which favorites among the spammers or use an IP address that has been used by spammers in the past. Thus, a reliable Anti Spam solution is one, which minimizes these false positives by adopting a comprehensive anti spam approach by examining both the message content as well as the history of the sender. Moreover, an effective anti spam software is one, which learns the user preferences by analyzing his behavior towards some particular messages. For instance, most of us may delete the messages containing the word ‘viagra’ but some medical organizations may not do so.

Thus, while no Anti Spam software is perfect, still we should use them to reduce the risk of getting plagued by the menace of spam mails.

There are different types of spam on the Internet. One is the "Congratulations, you won!" E-mail, also known as e-mail fraud. They offer the possibility of a cut of millions of dollars that the sender is trying to obtain illegally transferred out of some banana republic in the middle of nowhere. These emails asking to send information to provide the account number and a fax number provided. Soon you will be sending requestincreasing amounts of money to them – and sees the fraud. And if you're naive enough to send them money, but never received a penny cut your alleged "see."

I think I can say that we all hate spam! And no one can e-mail account with say they have 100% immune to this crime were against. Nobody likes to go to their mailbox and find all the junk mail that is unsolicited spam. So what we can to protect us from this threat?

Firstto everything and you kept your anti-virus and anti – spam software updated and current. An e-mail package to install spam filters that ISPs to prevent spam that you receive are not. Good spam filters are in the form of software or hardware. with the event that e-mails from people who do not know, but can communicate simply use the black list of another function blockE-mail.

Another thing to avoid is to publish public e-mail on the Internet. This is because a spammer can scratch your e-mail from a site you visited and which is in their database. Try not disclose your e-mail during the visit on the Internet forums and chat rooms. If you have your e-mail, you must use a non-business to create personal address or account to another account allows for communication on these sites. For GuaranteedEffect, the email security service provider to block all unsolicited e-mail before it reaches the network and this way you can avoid all spam.
